If I'm not mistaken, the PCI spec specifically dictates that PCI chipsets will run in the range from 25-33MHz. 75MHz Pentiums are not "premium" processors. :-) Now, the only thing wrong with 60/66MHz parts is that they're a "legacy" design. A P66 probably does run faster than a P75 in many circumstances. But the 60 and 66MHz parts were built with the original 5-volt design. If you have a motherboard old enough to have one of these chips in it, it's probably also too old to run any of the newer CPUs. Everything from the P100 on up uses a physically slightly different design, with a 3.3V (or somewhere a little over 3) voltage. I don't remember whether the P75 uses the old socket or the new one, but I would lean toward betting on the new one. So, avoid P60/66 systems simply because they will be much harder, and potentially more expensive, to upgrade. >People still living off their parents upgrade their systems quite >reguarly here at my University (1.5hrs from Silicon Valley).

Well, if you DID get a 75MHz Pentiums system, make sure you pay the right price for its "crippled" performance. Then, if at all possible (i. e. the motherboard supports it, and you can afford it), yank that sucker out, get a P100, minimum, and crank it up. ----------------------------------------------------------------------------- Michael L.

May I ask, did you try thinking about this yourself?: http://www.Intel.com/ http://www.Cyrix.com/ http://www.AMD.com/ Another very interesting site: http://www.x86.com/. It's pretty simple for real Pentiums (or 486s). Anything that is an even multiple of 33 1/3 (read things as 133.3... 166.667...) runs the memory bus at 66 2/3 MHz (i. e. "166"MHz Pentium is 2.5 * 66.67MHz). Anything that isn't an even multiple of of 33.3, and is an even multiple of 30, runs the PCI bus at 60MHz. The only other option that's left is multiples of 25 (75MHz Pentiums). The PCI bus on a Pentium runs at half the memory bus speed (the speed from the CPU to memory and cache). 486s run the memory bus at the same speed as the PCI bus (i. e. 30 or 33.3MHz in most cases). Older VLB 486s preferred multiples of 40MHz, since many VLB cards could do 40MHz, but PCI is not spec'd to run that fast. AMD and Cyrix muddied everything with their weird ratings. At least they use the same rating system. Their chips are rated for how fast they run relative to a true Pentium. I. e. a P133+ runs as fast, or slightly faster than, a 133MHz Pentium on their mix of tests. To find its true bus speed, consult tables on their web sites (or the person you're buying it from *should* be able to tell you). All of this information is on their respective web sites. ----------------------------------------------------------------------------- Michael L.

I have all the FACTS right -- I know exactly what I am talking about. I typo'd the original post (when I accidentally typed PCI where I meant memory bus), which is different from not getting the "facts" right. >``Even multiplier misses >the fact that there are 1.5, and 2.5 multipliers!!!''. I never once mentioned the word "multiplier". I did not discuss the motherboard clock multiplier setting. I discussed multiples of a value. 100 is an even multiple of 33 1/3. It's true that a 100MHz Pentium generally runs at 1.5 * 66 2/3 MHz, but that's not what I was discussing. The original post specifically asked about chip speeds and bus speeds, not multiplier settings. >Memory bus >speed should generally not be specified with 2 digits beyond the >decimal point as it depends heavely on the clock chip and/or oscillator >used in a design. I was specifically trying to make a general observation. That's why the first time I wrote the numbers, I wrote "33 1/3" and "66 2/3". Unfortunately, it's very awkward to write fractions in ascii test, especially when following them by a unit, such as "MHz". So, I used 33.33 and 66.67 to approximate 33 1/3 and 66 2/3. Moreover, if those aren't fairly close to the real figure, and we're truly talking about 33 and 66MHz, then we're also talking about 132MHz, 165MHz, and 198-199MHz Pentiums. I doubt there are any decent motherboard manufacturers out there really doing something stupid like that. Using "166" and "133" is merely a convenient way for them to say "133 1/3" and "166 2/3". >Here, express it the way that most motherboard documents do: That's fine. Very nice table, but not as summary-oriented as I had attempted to be. I figured if they wanted multiplier settings for their motherboard, it would be just as easy for them to look it up in their motherboard's manual, as to read it here. >Rated External Clock External to PCI Bus > CPU and Memory Bus Internal Clock Clock > MHZ MHZ** Multiplier MHZ > > 75 50 1.5 25 > 90 60 1.5 30 > 100 50* 2 25 > 100 66 1.5 33 > 120 60 2 30 > 133 66 2 33 > 150 60 2.5 30 > 166 66 2.5 33 > 180 60 3 30 > 200 66 3 33 > >* The Pentium 100 can be run at either 50MHz external clock with a > multiplier of 2 or 66MHz and a multiplier of 1.5.

Yes, it's been said that the P5/200 runs barely faster than a P5/166 in many benchmarks, because the bus is saturated. ----------------------------------------------------------------------------- Michael L.

And, on top of that, I think calling Intel's 512K cache the normal version is unreal. That chip is running (or was when last available) $600-650 each in 256K cache versions, and DOUBLE that in 512K cache versions. Under that kind of marketing plan, the cheaper one isn't 'bargain basement'. I think paying an extra $600 for an extra 256K of cache is kinda strange. > ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@eng.umd.edu | communications topic, C programming, and Unix. 9120 Edmonston Ct #302 | Greenbelt, MD 20770 | I run Journey2 and n3lxx, both FreeBSD (301) 220-2114 | version 2.2 current -- and great FUN! ----------------------------+----------------------------------------------- From owner-freebsd-hardware Tue Oct 1 22:01:17 1996 Return-Path: owner-hardware Received: (from root@localhost) by freefall.freebsd.org (8.7.5/8.7.3) id WAA02808 for hardware-outgoing; Tue, 1 Oct 1996 22:01:17 -0700 (PDT) Received: from lserver.infoworld.com (lserver.infoworld.com [192.216.48.4]) by freefall.freebsd.org (8.7.5/8.7.3) with ESMTP id WAA02800 for ; Tue, 1 Oct 1996 22:01:15 -0700 (PDT) From: BRETT_GLASS@infoworld.com Received: from ccgate.infoworld.com (ccgate.infoworld.com [192.216.49.101]) by lserver.infoworld.com (8.7.5/8.7.3/GNAC-GW-1.2) with SMTP id WAA16388; Tue, 1 Oct 1996 22:01:03 -0700 (PDT) Received: from ccMail by ccgate.infoworld.com (SMTPLINK V2.11) id AA844232194; Tue, 01 Oct 96 22:51:08 PST Date: Tue, 01 Oct 96 22:51:08 PST Message-Id: <9609018442.AA844232194@ccgate.infoworld.com> To: richard@pegasus.com (Richard Foulk), freebsd-hardware@FreeBSD.org Subject: Re: H/W recommendation Sender: owner-hardware@FreeBSD.org X-Loop: FreeBSD.org Precedence: bulk > This isn't quite the way cache works.

I never stated that the cache would (or should!) hold the whole kernel. It will, obviously, hold some data and user code. But it's a time-tested rule of thumb that, to a first approximation, your cache should equal the size of the kernel. (In the case of UNIX, the kernel should be trimmed to include only the devices that are actually present).

I wish I had the time to go calculate what a 1MB 4 set associtive seperate I/D write allocating cache would do for a Pentium 200 running FreeBSD, but I suspect quite a lot! It would probably do very little for the Pentium Pro, given that the internal 256K cache is already set associative and non-blocking. The current design of direct map external caches does pretty much top out at 256K, but when you add associative sets and split the I and D you eliminate some real bottlenecks (like large bcopy'ies that end up displacing all your cached code in the external cache :-(). An external really fast memory to memory DMA engine might be cheaper and give you the same overall system performance boost :-). Too bad the dreaded DMA on x86 machines is still based on the stupid old ISA DMA controller. Hummm... can I make a 2940 into a DMA engine, nahh.. the PCI bus is too slow compared to the 176 or so MB/s of usable memory bandwidth :-(. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD From owner-freebsd-hardware Tue Oct 1 22:47:54 1996 Return-Path: owner-hardware Received: (from root@localhost) by freefall.freebsd.org (8.7.5/8.7.3) id WAA07508 for hardware-outgoing; Tue, 1 Oct 1996 22:47:54 -0700 (PDT) Received: from mx.serv.net (mx.serv.net [199.201.191.10]) by freefall.freebsd.org (8.7.5/8.7.3) with ESMTP id WAA07492 for ; Tue, 1 Oct 1996 22:47:40 -0700 (PDT) Received: from MindBender.serv.net by mx.serv.net (8.7.5/SERV Revision: 2.30) id WAA20338; Tue, 1 Oct 1996 22:47:30 -0700 (PDT) Received: from localhost.HeadCandy.com (michaelv@localhost.HeadCandy.com [127.0.0.1]) by MindBender.serv.net (8.7.5/8.7.3) with SMTP id WAA21553; Tue, 1 Oct 1996 22:47:16 -0700 (PDT) Message-Id: <199610020547.WAA21553@MindBender.serv.net> X-Authentication-Warning: MindBender.serv.net: Host michaelv@localhost.HeadCandy.com [127.0.0.1] didn't use HELO protocol To: BRETT_GLASS@infoworld.com cc: "Rodney W.

Please don't group these together, because they don't belong in the same category when talking about this. It doesn't much depend on the cache, with the Pentium, because at 3x the bus speed, it's going to saturate the bus no matter how much cache you have. Because the cache is on the far side of the bus. No matter how much or how fast your cache is, you still are only running it at ~66MHz (75MHz in some of the Cyrix motherboards -- which isn't "standard" [yet?]). The Pentium Pro is a whole different ball game precisely because of its on-chip cache. The cache speed runs at the CPU speed, which means its always a single-cycle access, no matter how fast the CPU. This was done specifically to address this problem. Otherwise, the P6 wouldn't be able to scale much higher than 200MHz (with a ~66MHz memory bus, anyway), either. Coupled with the faster cache is the fact that it is non-blocking at up to four cache misses. >A >Pentium Pro with a built-in 512 KB level 2 cache usually won't starve, even >on UNIX boxes. (To put things in perspective, a typical FreeBSD kernel, >with unnecessary drivers removed, is about that size.) I think you need to do some more detailed testing. It *can* starve, given the right mix of work to do. Even with 16MB of cache. Granted, the misses won't take as long to fill, but it will still stall. >But the bargain >basement version of the Pentium Pro, with the 256 KB cache, will drag in >the same configuration. Unfortunately, far too many clone vendors just >HAPPEN not to mention in their ads that they're including the cheaper CPU. Do you have any proof of this? I think you're speculating. And, I don't know how you can call the 256K P6 the "bargain basement" when it costs as much as the *highest* speed Pentium. Plus the fact that 512K P6s are *twice* as expensive, and hard to get. I would say the 512K model is *definitely* a _premium_ model. But if you like paying $1200 for your processors, you can think of them any way you like. :-) Besides, as already pointed out above, the 256K Pentium Pro cache is already *way* faster than any size cache on a Pentium. Plus, with a 256K cache you're already taking about hits in the 90+% range. 512K would be nice, but its definitely at the far side of diminishing returns. Where the 512K model *would* be very valuable is in a four-way SMP box, since you start getting a lot of bus contention in that kind of environment. >I'd like to see a megabyte cache on board.

I've done benchmarks of heavily-loaded servers with and without the proper chip. Intel originally wanted *all* Pentium Pros to have half a meg of cache on board (see their earliest announcements), and for good reason: it's needed.

I have been through a long line of 34780s, and they have all died on me. The last one is just doing it now.
